Subject: tools/ceph-dencoder: register dencoders in "lib" in dev env
X-Git-Tag: v18.0.0~383^2

tools/ceph-dencoder: register dencoders in "lib" in dev env

if "CMakeCache.txt" is found in current directory, try to load
dencoder shared libraries  from ./lib. this heuristics is used by
`ceph.in` also for relaunching itself to get access to python
bindings.
